Sorry I am having trouble accessing your Plex skill right now
I just set up a pair of music libraries tonight. When I say "Alexa ask Plex to play Music" or "Alexa ask Plex to play " or "Alexa ask Plex to play " all I get for a response is "Sorry I am having trouble accessing your Plex skill right now". I can use Alexa to control playback through Plex or see what is on-deck or start a video. I've set up (although perhaps unnecessarily) port forwarding in my router and can reach my Plex server from outside my network and stream music outside my network.
I really want to be able to play music from my Echo Dot any help would be appreciated.
